🚙 Trial Truck Challenge

International Trial Truck Series (ITTS)

Where scale meets skill.
Built trucks. Real terrain. No easy resets.

🏁 Overview

The Trial Truck Challenge is the core ITTS event — designed to push both driver and machine to the limit.

Expect a true test of:

  • Precision driving
  • Throttle control
  • Recovery skills
  • Teamwork

🌍 Event Stages

Drivers will take on three demanding off-road stages:

🪨 Rock & Technical Section
Tight gates, big rocks, and precise lines.

🌧️ Mud & Water Section
Low grip, deep ruts, and unpredictable terrain.

🛣️ Endurance Trail
Long-distance driving where consistency is key.

Clean driving and smart decisions are everything.
Time is only used as a tie-breaker.
